I'm no professional or anything so I man not be right, but I think your people look kind of..stiff. Like the demon/animals look cool but the people I guess aren't as detailed. You need to make them come alive from the paper, to look real. Maybe add some wrinkles, some movement to their hair, and eyes x) lol :b it looks good besides that. The proportions are good, which is sometimes hard to get their forearm (if that's what it's called) is a bit too long, or at least it looks that way in the drawing. It's really good so don't think I'm only saying what's wrong I really like they demons and how the girls demon is scary looking lol :b
